METHOD OI' COOLING CANNED GOODS AND APPARATUS USED IN SUCH METHOD Application'led December 10, 1927. Serial No..I2/39, 249.

The resent invention relates to a' method of cooling 'canned goods and to an apparatus used in such method, and an object of the 1nvention is to provide for cooling eectively .a number of cans in bulk.

To'these and other ends, the invention consistsin the method hereinafter set forth as well as the apparatus-hereinafterdescribcd;

, apparatus.

' v Prior to this invention the cooling of cannedI goods in bulk 'has been accomplished in a number of ways, one of wlnch consists in passing the canned goods in `open- Work baskets or containers through "a tank or vat of coldv water. This methodhas resulted in the cooling of those cans'on the neath.

outermost portions of the basket in which the cans-are arranged, but those cans arran ed at the vcenter of thebasket maintain a ot conditionbecause thecold water is heated before it reaches such cans. .In this invention, the cold water is caused to circulate upwardlythrough the bottom of the basket from the bottom of the tank, and if the cans are moved through the tank they are subjected to two currents, one horizontally or in 'the direction of the length of the tank, due to the movement of the basket in the tank, and the other vertically from -the bottom of the tank. In carrying out this invention, the tank 1 is an elongated struct-ure similar to that vnow in usb and through this tank the canned goods .N

Q'are moved in the direction of the length of the tank. These cannedl goods are arranged in bulk, in this instance, in an open work basket 3 being positioned in the basket =on their ends and in different layers, the bottoms ofthev cans of one layer resting on the upper ends of the cans of thelayer next be- The baskets may be moved through the tank or receptacle 1 in any suitable manner. In this instance, their bails 1 are suspended from hooks 5l on a Wheeled carrier -6 Vtravelling on a trackway 7 extending longitudinally of the tank 1. The movement of the basket through the carrier creates a cur' rent longitudinally of the tank past the canned goods. i

With the end in view of producing an upward current between the cans, one vor more air pipes 8'may be provided extending longitudinally of the tank and each provided with a longitudinal series of jet openings. These pipes, in this instance, are located near the middle of the tank and near the vertical center of the basket. The issuing of cold air from these jet openings 9 creates a current upwardly through thel bottoms of the baskets and between the cans therein, the water theny flowing outwardly toward the sides of the receptacles and then downwardly to theAr bottom of the tank, as indicated by arrows 10,-Fig. 3.

It will thus be seen that there has been provided an effective means for 'cooling canned goods in bulk. The 'canned goods while l arranged in an open work basket submerged in a liquid bath are subjected to a cold water current passing upwardly through the open work basket from the bottom thereof and between the cans at the center of the open work basket. At the same time the open work basket with the canstherein is moved bodily through an elongated tank' so as to create a currentvabout the cans, thus preventing discoloring of the product.

This method eliminates the polishingv of the cans before they are shipped and the upward current prevents the formation of the lusual film or dirt coating which collects on the cans under theold methods. y

What I claim as my invention and desire to secure by Letters Patent is:

1. A method of cooling canned goods in bulk which consists of moving an openwork basket bodily through a body of cold liquid with the cans submerged in such liquid, and creating a current upwardly-between the cans from the bottom of the receptacle.

2. A-method of cooling canned goods in bulk which consists in moving horizontally through `a liquid body an openwork basket COMPANY, 'OF EAST WILLIAMSON, NEW YORKA CORPORATION 0F I with the cans arranged thereinon their ends, and projecting yupwardly air jets into the liquid body beneath the basket to create an upward current between the cans in the basket.

3. An apparatus for cooling canned goods in bulk com rising a tank containing the cooling liqui an openwork basket containing the cans in bulk, and means for 'creating an upward current of the liquid in the tank through the bottom of said openwork receptacle.

4. An kapparatus for coolingcanned goods in bulk comprising an elon'ated tank for containing the cooling liquida, an openwork basket for 'containing the canned goods,

-means guiding said basket in a submerged condition longitudinally of the tank, and an air pipe extending longitudinally of the tank near the middle of the tank and beneath' the basket,' said pipe haying et openings discharging upwardly.
